Embodiment Construction

[0026] The wind turbine generator set, the main bearing cooling system and the cooling control method thereof according to the embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0027] like figure 1 As shown, the wind power generating set includes a nacelle 6, a fixed shaft connected to the nacelle 6, a main bearing 2 arranged in the fixed shaft, a moving shaft 8 passing through the main bearing 2, and the like. Among them, the outer ring of the main bearing 2 is installed in the fixed shaft hole, and remains stationary together with the fixed shaft, and the inner ring of the main bearing 2 is installed on the moving shaft 8, and the follower shaft 8 rotates together. The moving shaft 8 is connected with the rotor support and the impeller system, and rotates with the impeller system. During the working process of the wind turbine, the main bearing 2 will generate heat, so that the operating temperature of the ...

Abstract

The invention provides a wind generating set, a main bearing cooling system thereof and a cooling control method. The main bearing cooling system of the wind generating set comprises a semiconductor cooling part and a power supply control part, wherein the semiconductor cooling part is provided with a cold end absorbing heat and a heat end releasing heat, and the cold end is connected with a main bearing to be cooled; and the power supply control part is connected with the semiconductor cooling part, supplies power to the semiconductor cooling part and controls the semiconductor cooling part. The main bearing cooling system of the wind generating set is used for cooling the main bearing, reliability is high, controllability is good, and no noise or vibration exists.

Description

technical field [0001] The invention relates to the field of cooling equipment for wind turbines, in particular to a cooling system and a cooling control method for a wind turbine and its main bearing. Background technique [0002] The large-scale wind turbine has gradually become a trend, and the large-scale wind turbine will inevitably lead to the large-scale of its main bearing, which makes the load of the main bearing increase sharply, and brings many challenges to the safe and reliable operation of the main bearing. The operating temperature of the main bearing is an important factor for its reliable operation. In order to ensure the reasonable life of the main bearing of the wind turbine, in addition to fully considering the relevant requirements in design, manufacturing, processing and assembly, the on-site operating temperature of the main bearing should be controlled within a reasonable range to avoid premature failure of the main bearing. Power generation companie...
